Remote controlled underwater manta ray toy

Here's a novel twist to the remote control toy: an underwater manta ray. The really cool thing about it is that you can perform tricks and moves in three dimensions (like a plane) but with much less concern for crashing the thing into the ground at high speed!

From the product description:

Forefinger triggers on the underside of the remote enable independent pitch for each thruster, providing control for steep, powered dives to the bottom of pools and rapid ascents. Thumb toggles on the topside of the remote allow for independent thrust operation of each shrouded propeller, providing the ability to move forward, backward, make left and right turns, barrel rolls, or complete underwater loops--even intricate submerged Immelmann turns.

I have no idea what "Immilmann turns" are, but the range of motion sure sounds like a lot of underwater fun.
